The NM-HDV2 network module converts voice and fax into IP packets or frames that can be transmitted
as VoIP over a variety of transport technologies (channelized T1, Frame Relay, Asynchronous Transfer
Mode [ATM], and others).
Packet Fax or Voice DSP Modules
The packet fax or voice digital signal processor (DSP) module (PVDM2) is available in five
stock-keeping units (SKUs):
